Abstract

PROBLEM TO BE SOLVED: To obtain an optical module with which it is possible to easily align an optical multiplexer/demultiplexer while being held in contact with an adhesive and a method for manufacturing the same.SOLUTION: An optical multiplexer/demultiplexer 2 made of glass is fixed on a pedestal 1 by a UV adhesive 3. A metal block 6 smaller in size than the optical multiplexer/demultiplexer 2 is fixed on the top face of the optical multiplexer/demultiplexer 2. This makes it unnecessary to grasp the optical multiplexer/demultiplexer 2 made of glass that is susceptible to breakage. Furthermore, since a gripping tool 9 firmly holds the metal block 6, the optical multiplexer/demultiplexer 2 will in no case lose to the viscosity of the UV adhesive 3 and come off. As a result, the optical multiplexer/demultiplexer 2 can be easily aligned while being held in contact with the UV adhesive 3.SELECTED DRAWING: Figure 1

Description

  The present invention relates to an optical module having an optical multiplexer / demultiplexer for multiplexing or demultiplexing light and a method for manufacturing the same.

  In the conventional optical module, the lens is aligned at a desired position using a lens holder in which the lens is inserted and a holder guide, and the member is fixed by laser welding or the like. The material of the lens holder and the holder guide is stainless steel, Kovar, or the like (for example, see Patent Document 1). In addition, an optical module using glass Prism as an optical multiplexer / demultiplexer has been proposed (for example, see Non-Patent Document 1).

  In the optical module of Non-Patent Document 1, it is necessary to prevent the glass optical multiplexer / demultiplexer from being damaged when the optical multiplexer / demultiplexer is gripped for alignment. For this reason, for example, it is necessary to hold the optical multiplexer / demultiplexer using an adsorption device having a large area. The optical multiplexer / demultiplexer is fixed between the bases by an adhesive. If you try to align the optical multiplexer / demultiplexer in contact with the adhesive using the adsorption device, the glass optical multiplexer / demultiplexer will be removed from the adsorption device due to the viscosity of the adhesive and adjusted at an appropriate position. It is difficult to core. Therefore, after aligning the optical demultiplexer from the adhesive, the optical multiplexer / demultiplexer is lowered and brought into contact with the adhesive. Accordingly, misalignment occurs when alignment is performed at a position different from the originally fixed position and the optical multiplexer / demultiplexer is lowered. As a result, there is a problem that the optical multiplexer / demultiplexer cannot be fixed at an optimum position.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an optical module capable of easily aligning an optical multiplexer / demultiplexer while being in contact with an adhesive, and a manufacturing method thereof To get.

  The method of manufacturing an optical module according to the present invention includes a step of fixing a metal block having a size smaller than that of the optical multiplexer / demultiplexer on an upper surface of a glass optical multiplexer / demultiplexer, and the metal fixed to the optical multiplexer / demultiplexer. The optical multiplexer / demultiplexer is moved by moving the metal block and the optical multiplexer / demultiplexer in a state where the block is held by a holding jig and the lower surface of the optical multiplexer / demultiplexer is in contact with the UV adhesive applied to the upper surface of the base. And after aligning the optical multiplexer / demultiplexer, UV light is transmitted through the optical multiplexer / demultiplexer and irradiated to the UV adhesive to cure the UV adhesive. It is characterized by.

  In the present invention, by providing a metal block on the upper surface of the optical multiplexer / demultiplexer, it is not necessary to hold a glass-made optical multiplexer / demultiplexer that is easily broken. Moreover, since the holding jig can hold the metal block firmly, the optical multiplexer / demultiplexer does not come off due to the viscosity of the UV adhesive. As a result, the optical multiplexer / demultiplexer can be easily aligned in a state where it is in contact with the UV adhesive.

The light is totally reflected by the filter 4b serving as a stop band, is transmitted through the optical multiplexer / demultiplexer 2, is totally reflected by the mirror 5, is transmitted through the optical multiplexer / demultiplexer 2 toward the filter 4a, and the wavelengths λ1, λ2, and λ3 are the stop bands. The light is totally reflected by the filter 4 a and passes through the optical multiplexer / demultiplexer 2 to become a part of the outgoing collimated beam light 8.

  Then, the manufacturing method of the optical module which concerns on this Embodiment is demonstrated. FIG. 2 is a perspective view showing the method for manufacturing the optical module according to Embodiment 1 of the present invention. First, a metal block 6 having a size smaller than that of the optical multiplexer / demultiplexer 2 is fixed to the upper surface of the optical multiplexer / demultiplexer 2 made of glass.

  Next, the metal block 6 fixed to the optical multiplexer / demultiplexer 2 is held (mechanical chuck) by a metal holding jig 9 such as SUS. The metal block 6 and the optical multiplexer / demultiplexer 2 are moved in the X, Y, Z directions and θy, θx directions while the lower surface of the optical multiplexer / demultiplexer 2 is in contact with the UV adhesive 3 applied to the upper surface of the base 1. The optical multiplexer / demultiplexer 2 is aligned at the optimum position. Thereafter, the UV light source 10 irradiates the optical multiplexer / demultiplexer 2 with the UV light 11 from above. As a result, the UV light 11 is transmitted through the optical multiplexer / demultiplexer 2 and irradiated to the UV adhesive 3 below the optical multiplexer / demultiplexer 2 to cure the UV adhesive 3.

  As described above, in this embodiment, by providing the metal block 6 on the upper surface of the optical multiplexer / demultiplexer 2, it is not necessary to hold the glass optical multiplexer / demultiplexer 2 that is easily broken. In addition, since the holding jig 9 can firmly hold the metal block 6, the optical multiplexer / demultiplexer 2 does not come off due to the viscosity of the UV adhesive 3. As a result, the optical multiplexer / demultiplexer 2 can be easily aligned while being in contact with the UV adhesive 3. In particular, it is extremely effective for a product such as an optical integrated module in which a mounting dimension in the X direction cannot be secured sufficiently.

  Further, since the UV light 11 passes through the optical multiplexer / demultiplexer 2 made of glass, the optical multiplexer / demultiplexer 2 can be fixed at the optimal position aligned. At this time, the metal block 6 having a smaller size than the optical multiplexer / demultiplexer 2 does not block the UV light 11.

The hexagonal two sides of the metal block 6 are gripped by the gripping jig 9, and the optical multiplexer / demultiplexer 2 is moved in the X, Y, Z directions and the θy, θx directions. Alternatively, the hexagonal three sides of the metal block 6 can be gripped by the gripping jig 9. Thereby, since the metal block 6 can be mechanically chucked from three directions, the design freedom of the gripping jig 9 and the mounting workability are improved. Other configurations, processes, and effects are the same as those in the first embodiment.

Embodiment 3 FIG.
FIG. 4 is a perspective view showing an optical module and a gripping jig according to Embodiment 3 of the present invention. A hole 12 is provided in the side surface of the metal block 6. The metal block 6 is gripped by the gripping jig 9 while the lateral projections 13 of the gripping jig 9 are inserted into the holes 12 of the metal block 6. Thereby, the metal block 6 can be gripped more firmly. Other configurations, processes, and effects are the same as those in the first embodiment.

Embodiment 4 FIG.
FIG. 5 is a perspective view showing an optical module according to Embodiment 4 of the present invention. Instead of the metal block 6, the height of the optical multiplexer / demultiplexer 2 is increased, and a plurality of holes 14 (two or more) are provided on the upper surface of the optical multiplexer / demultiplexer 2. The hole 14 may be straight or diagonal.

  Then, the manufacturing method of the optical module which concerns on this Embodiment is demonstrated. First, a glass-made optical multiplexer / demultiplexer 2 having a plurality of holes 14 on the upper surface is prepared. Next, the optical multiplexer / demultiplexer 2 is held by the holding jig 9 while inserting a plurality of downward projections of the holding jig 9 into the plurality of holes 14 of the optical multiplexer / demultiplexer 2. The optical multiplexer / demultiplexer 2 is moved in the X, Y, Z and θy, θx directions while the lower surface of the optical multiplexer / demultiplexer 2 is in contact with the UV adhesive 3 applied to the upper surface of the base 1. Align the corrugator 2. Thereafter, the UV light 11 is transmitted through the optical multiplexer / demultiplexer 2 and irradiated onto the UV adhesive 3 to cure the UV adhesive 3.

  By inserting the protrusions of the holding jig 9 into the plurality of holes 14 of the optical multiplexer / demultiplexer 2, the optical multiplexer / demultiplexer 2 can be firmly held without breaking. As a result, the optical multiplexer / demultiplexer 2 can be easily aligned while being in contact with the UV adhesive 3. Further, the optical multiplexer / demultiplexer 2 can be gripped without mounting an additional member called the metal block 6, and the cost can be reduced.

Embodiment 5. FIG.
FIG. 6 is a perspective view showing an optical module according to Embodiment 5 of the present invention. Instead of the metal block 6, the height of the optical multiplexer / demultiplexer 2 is increased, and one hole 15 is provided on the upper side surface of the optical multiplexer / demultiplexer 2.

  Then, the manufacturing method of the optical module which concerns on this Embodiment is demonstrated. First, a glass-made optical multiplexer / demultiplexer 2 having holes 15 provided on the upper side surface is prepared. Next, the optical multiplexer / demultiplexer 2 is held by the holding jig 9 while inserting the cylindrical protrusions in the horizontal direction of the holding jig 9 into the holes 15 of the optical multiplexer / demultiplexer 2. The optical multiplexer / demultiplexer 2 is moved in the X, Y, Z and θy, θx directions while the lower surface of the optical multiplexer / demultiplexer 2 is in contact with the UV adhesive 3 applied to the upper surface of the base 1. Align the corrugator 2. Thereafter, the UV light 11 is transmitted through the optical multiplexer / demultiplexer 2 and irradiated onto the UV adhesive 3 to cure the UV adhesive 3.

  By inserting the protrusion of the holding jig 9 into the hole 15 of the optical multiplexer / demultiplexer 2, the optical multiplexer / demultiplexer 2 can be firmly held so as not to break. As a result, the optical multiplexer / demultiplexer 2 can be easily aligned while being in contact with the UV adhesive 3. Moreover, since the hole 15 of the optical multiplexer / demultiplexer 2 can be formed by a single process, the processing cost can be reduced.
